SYSTEMS OF SOLID OXIDE FUEL CELLS WITH IMPROVED GAS CHANELLING AND HEAT EXCHANGE Russian patent published in 2012 - IPC H01M8/02 H01M8/24 

FIELD: electricity.

SUBSTANCE: system of solid oxide fuel cells contains the following: one or more tubular fuel cells with longitudinal axis and each cell includes anode, cathode and electrolyte; central supporting element communicating with each of the above tubular fuel cells, moreover this central supporting element contains inner longitudinal member that forms inner and outer longitudinal channels; at that outer longitudinal member is concentric in regard to inner longitudinal member and is located around it. Inner longitudinal member is designed to supply fuel to one or more anodes mentioned above and outer longitudinal member is designed to supply oxidiser to one or more cathodes mentioned above, at that one or more tubular fuel cells are located around central supporting element; one or more anode output flowing channels communicating with one or more anodes and directing anode exhaust from one or more anodes; one or more cathode output flowing channels communicating with one or more anodes and directing cathode exhaust from one or more cathodes; current collector located around central supporting element contains reduction chamber, which communicates with one or more anode output channels mentioned above, but not with cathode output channels; current collector located inside reduction chamber and electrically connected to each tubular fuels cells mentioned above; afterburner communicating with reduction chamber and one or more cathode output channels, at that afterburner is able joining anode and cathode exhaust from anodes and cathodes.

EFFECT: improvement of operating efficiency by improved regulation of temperature and current collection.
